  • Research Interests and Activities:
    Dr. John D. Aber has worked on nutrientcycling in temperate forest ecosystems since 1973. Research activities haveincluded forest canopy structure and function, forest production, litter productionand decomposition, production allocation and fine root dynamics. With particularinterests in carbon and nitrogen dynamics, he has approached research usingseveral methods and tools including intensive and extensive field studies, traditionaland experimental remote sensing (including high spectral resolution instruments),computer modeling and spatial analysis. Dr. Aber is also a PI at the HarvestForest LTER site, where he has conducted a 12-year (and continuing) experimentalnitrogen amendment project. His research work has focused on the problem ofnitrogen saturation and resulting impacts on forest health and streamwater quality.

    Distinguished Awards and Memberships:
